Personally I love this not sure about the colors you chose for the test or that box around it!! but i do like this signauter alot and i don't no if its the render or not but the eyes are a different color kinda bugs me lol Great Job !!
I find the sig a bit bright as it hurts my eyes looking at the render. Imo text sucks. Its too centered offset it in some way
lighting is ok but yes the text looks distracting. if you were supposed to make the text match the eyes then use less pastel and bright colors.... use some washed out colors like in the eyes.....
