... like I said I'm a freshman in high school, I need to learn all that I can.
You're doing fine. Heaven help me if the work I did as a high school freshman should ever see the light of day.
I'm still not a fan of the proportions. But really, don't let that stop you. Any job boils down to what you can sell to your client. Personal aesthetics are just that ... personal. And if you showed any group of people your version vs. my version, some would like yours better and some would like mine. In the end there is no right choice.
Just make the best choices that you can and try to have a rationale for them. Sell it to the client, make a buck or two and buy yourself a beer. You deserve one.
