I dont know why but i prefere the aguero one more than the reus one due to the reus one looks like theres so many layers that are transparent and its hurting my eyes to see it, idk if its because reus is too large probs why but yeah I think the aguero one stands out more.
But also theres some problems with the aguero one aswell. if you look at the players neck, you can see the part of the wing of the manchester city badge which looks bad so if you went over it and erased that part of the badge then that would be good.
Overall they look really good, keep improving and you will get success.
