Building Up Barriers

A picture about growing up and moving apart.

I don't even know how long I've been working on this one. =.= It's been on my computer for months waiting to be completed. Somehow the shading just didn't want to work with me. But i suppose i can live with it like this.

I also tried a more fun sort of way to do clouds(Which now I can't remember how to do, so they'll never be repeated in my pictures...)
