Since our background color here on GD should be close, it looks like it holds up well at various resolutions. I might suggest having a solid yellow vertical bar above your "M" in the 16x16 image as the light color combined with the yellow makes it a little difficult to make out. Just fill in the stripes that shouldn't have blue.

I think the logo comes off a little cheap as combining the initials like that is the first thing that pops into mind. On it's own is considered a cliché among professional graphic designers. Ideally your logo should tell something about what you do and be tailored to you. What sets up apart from other MBs? Is "mb" about plumbing, beauty, law, IT, art? Maybe you can add some shape to the letters to form something that connects to what you do?

If you really want a logo out of just the "m" and "b" I think you could do better than what you have. Pixelated look is yet another widely used cheap shortcut and comes off really generic and cold in my opinion. You should round some corners to add personality and sympathy into it but rather scrap the look and try to find inspiration from different fonts and come up with more creative way to combine the letter shapes. The letters "m" and "b" have interesting sharp and round corners and if I were you I would try to play more with ideas about that.

Also quick note on the colors: logo is a shape. Think "Coca-Cola". The text is their shape and red is their color and you've seen it combined in a million ways. A good logo works in black and white and you should not have a logo that requires 2 or more color shades to be readable. Your current logo doesn't work if you want to engrave it into laptop cover for example.

You should first come up with a logo shape and then think about "trademark colors" you want to use. Then you can build couple of logo variations with different image ratios for different uses (banners, headers, thumbnails, icons, wallpapers). Also note that if you're professional you should work on the logo with vector graphics or have it vectorized when you're done with the design.

Gosh, I hope I didn't come off too strong. It's just I've worked with logos quite a bit both designing and using them in advertising.

Ok, now you're getting somewhere with the last version.

Well I'm sure you can come up with some shape that relates to software or IT in general. Pac-man, mouse cursor, enter key, ones and zeros, etc.If you come up with suitable one while developing your idea why not give it a try?

I think there mild unease with visual whitespace inside the M shape not correlating nicely to the 2 whitespaces inside the "B". It's probably the shape because area ratios 1:2:4 should be about right. Well this is just aesthetics

Noticed you could build a lowercase m out of the B shape by turning it 90 degrees? Could you get something out of it?

Just going to throw this out there: Your latest designs seem a little too similar to Milton Bradley as is.

Milton Bradley, looks like just another non-logo that is just text.

Since mb letters like any letter combination isn't too rare you can actually just Google image search you don't have identical design as someone else. Doing that search is also good eye opener if one thinks combining letters alone is original ;)

But don't be discouraged. It's not like you are building a huge international brand so perhaps it's not so important.

Since your first idea was to use color, I think you should go back to that. There's a lot of room to explore with colors.

Perhaps black only works better when you have a symbol for your identity (i.e the Nike symbol).

One image that helps me when I'm producing a graphic is this:

But note that I only come to that when I already have the design figured out. And I think that's what's missing in yours, the design.

It comes from mostly an idea or a statement. "I'm a software developer" is a start, but what else can you say about you and the work you do? This sort of brainstorming will make it easier for you to come up with a symbol (be it concrete or abstract) that you can define your identity with, and have your MB letter accompany that symbol in an elegant fashion.

PS: I'm interested in what others may have said about your logo. Please post the links to the Reddit thread etc.
