For a beginner, this is very good. You have a nice sharpen, blur going on, and your blending is pretty well done too. The colors don't clash that much either, which is good. What I'd give advice on is that your flow has it going to the left, but the left c4d is going up, which doesn't work well. Also, you don't have a lighting source. You need to find one, and put one in. IIn some cases, you don't, but for this one you might want one a bit to the top right-ish.
And for the main points, not all signatures need cinematic borders. Also, as a beginner, stay away from text unless you know how to use it. All in all, you did pretty well as a beginner.
