*Sigh*
Dude, if you're gonna give up immediately if everything you do isn't perfect in the first place, you're gonna be seriously screwed over for the rest of your life. Your alien ain't all bad- I've seen worse in major movies. But you're not gonna get something that everyone's gonna like (at least, not without a lot of practice), unless you agree to modify it a little according to what OTHERS wanna see, not just yourself. If you really just wnt to please yourself, and don't give a **** what anyone else thinks, or expect everyone to sit back and agree sycophantically with whatever you do, don't post stuff here. Go show it to, I dunno, your mom or something. If you post here, it's gonna get nitpicked. That's what we do. And if you sort through all the little peccadilloes, and take those ideas you're not totally opposed to, and can work in together properly, you'll end up with a cool-ass alien. Otherwise, your mom can tack it on your refrigerator. Your call.
There's nothing personal in it. You should know that, being a long-time HLPer. Want me to bring up some of the threads where I got not just nitpicked, but utterly TRASHED in? You begin, you're not so hot, you work at it, you get better. Repeat until you can con some poor fool into paying you. Lookit the crap I do now. Look at the crap I used to do. You think I figured out how to do stuff well on my own, with everyone just saying "Oh! Look at that textured sphere! It's perfect! I never thought of THAT!"?
