The SpiderMan one is my favorite, probably because of the render of him you used. The text on it needs to be changed, or the background needs to be changed color wise to match the text and render. I dont get what the dots are for on the second one, but try using more color. You have two colors there, green and brown, not a bad combo but that big green 3d cad render in there doesnt quite flow well and takes up a lotta bg space. The third one is good, just blend in the render with the bg and change up the text a little. 7/10 Overall for me. GJ, keep it up!
