1. 4/5(1M) - I really like this one. The background pops and looks good and detailed. There's clear render work with the logo/texture changes, however it doesn't really blend in with the background that well. I like the text used for the name and thinks it blends in with the background well, however the subtext was difficult to read and may have been too dark ultimately.
2. 3.5/5(850K) - I like the render here and think you did a great job recoloring the jersey, I do see some leftover parts from the initial render however by the render's shoulders and think you could do a better job cleaning those up in the future. Background-wise I think the empty space on the left side of the graphic left a lot to be desired but I thought the sparks were some cool effects, just that there wasn't much going on there besides it and the b&w background. The text was off to the side and although I do like it's appearance, did not really like its location.
Steps moving forward:
I would highly recommend making sure the renders blend with the background moving forward as it can really help with the appeal of a sig. Making sure text is easy to read as well as making it a focal point of the sig are also two factors that can lead to a better sig. Ensuring that there's little to no empty space in your sigs can help with getting better grades in the future as well.
