Critique on my Sail and Flag design.

[RunSeven]

I'm pretty new to PotBS (going on a week now) and I really like the idea of uploading my own content. I made my own sail and flag designs for my Society (just three friends and I so far) and I was wondering if you guys could give me any suggestions. I'm hoping they're ready to put up for voting.

Thanks in advance for any advice!

(I saw other people were putting the imagines into a little box at the bottom that said "attachment" but I wasn't sure how to do that, sorry for the size.)
