Rant: I just wanted to know how to draw pixel art. I'm trying to do an adventure game for the NES (and for the PCE later when I get the hangs of 6502) but f*ck I can't draw for shit. I just wanted to do character portraits that are somewhat like Bionic Commando like:
But everytime I try to do a portrait I fail miserably. Any ideas to help a shitty programmer be able to do shitty art?
If you want to do portraits that have hand-drawn artwork, then you should start working on your drawing skills. Anyone can learn to draw well enough to do portraits like those. The actual pixel work is a minor detail in comparison.
You could do what the artist in Bionic Commando did for many of the portraits and just create a base model and then re-work it for different faces.
For developing pixel art skills in general, you should start examining examples that excel in different ways, figure out details that make them work and try reworking them in different ways. Try taking some shaded colorful 16-bit graphics and rework them into proper NES (not just NES-like) graphics.
With all of this, you'll get better and better just from going through the motions.
