but apparently this is the best my skills would allow

I went through Familiar Coloring Contest 2017 Discussion, but didn’t really…. get a clarification for everything.

What program would be the best? I don’t have ANY program installed. and am a complete newbie when it comes to anything like this. Should I use a free program, or illegally download one? (Lel probably not even allowed, but it’s not like they can check.)

(I also have problems figuring out the no highlights/shadows, but apparently gradients are okay. My untrained eye can hardly tell those apart. ; _ ; Honestly, I’m not skilled enough to add gradients, but without those it will look TOO flat.)
