This is your first crest that actually really looks like a crest, well done! You're definitely improving.

You might, however, want to look into more creating your own artwork instead of compiling internet sources (the crest outline, for example, looks rather blown up to me and needs some anti-aliasing, same goes for the knight).

It's awful. Vitoria Guimaraes have one of the best crest's in world, dont need to change.
