has any of y'all, cant draw with shiz on paper, but can create masterpieces on blender, or whatever tool you use?

When you listen to a music piece in you mind, can you reproduce it on an instrument ? Not yet, but maybe with practise ? The key is practise, practise, practise, and after that, still practise. I'm a coder and I've pratised painting for a few years now , thought not enough, I'm quite satisfied with the result. Currently I'm involved in modelling, painting textures and icons, rigging and animation. By far I can't reach the quality of any professional artist, but I'm convinced, that I still have enough reserves left over to improve my skills.

Yes, I can't draw as well.
I wouldn't say, that my Blender models are masterpieces, but they are quite okay.

That's the reason why I use Blender to make sprites for my flashgames.
However, the issue is to draw the textures for the models.

Anything that's pretty geometric is 3D-friendly, which includes spaceships. There are also a lot of models for sale that you can pose, animate, and optionally recolor. But if someone who hadn't built up some art skills were to try to model a human from scratch, they would have a tough time.

Software such as ZBrush, MudBox, 3DCoat or Sculptris turn the act of character and organic model creation into an intuitive and very smooth process. I'd venture to say that just about anyone can create somewhat acceptable characters by way of an intuitive method such as sculpting. I've put my 4 year old niece in front of the computer with Sculptris up and she creates some quite convincing blob-like characters. They're not anatomically correct humanoids (those do take a bit more work plus plenty of reference material, but I still don't think they take any significant amount of 2D skill). But they're pretty awesome for a 4 year old kid who can't even color inside the lines.

The technical tools we have available provide a pretty strong disconnect between the skills required for different kinds of game artwork. If you are a 3D modeler, you do not need strong 2D skills. The two mediums are different. Tools allow you to sculpt organically, paint directly on the model using various textures, and import the models into other software for rigging and animation. Even texture painting these days is so much a process of painting directly on the model using broad strokes of color, heavily using procedural textures or textures derived from the real world, etc... Once upon a time, you wanted to have an eye for shading and highlighting, and while that still comes in handy, a non-2D artist can just bake ambient occlusion and shading maps directly from high-res sculpting, rather than trying to hand-shade the texture.

It's a different type of thinking for 3d work though, don't be discouraged.
...I'm not very good with 2d stuff either:)
