"This user has a very promising start with their sigs, but I think the main point of focus for their future work should be their composition. Every sig has an issue of not having multiple elements being equally important, which I think causes all of these to look really busy." -Kolt
I think Kolt's comment is the main point. However, I am going to award a bonus on top of these grades because I feel that is the point to an extent. I think the weakest point on these, that isnt something strictly style based, are the swaps. Mainly on the helmet logos. My rule of thumb is to get the logo warped and place on the helmet. Duplicate the warped logo. Set the bottom logo to multiply and the top on to screen. Lower the screen logo layer's opacity to mesh with the other. Lastly, add highlights and shadows on top of the logo. It should work for GIMP and PS. For warping, I use the perspective warp and Liquify/Move Pixel. I don't think every sig in this series is equal. However, I split the difference with other graders.
For your animated one, it is great you did it, but it isn't very exciting. The swap is one of your weaker ones and the text lacks the usual energy that you see in your others.
