Hi, OK I will try to give you some constructive criticism. You need to lower the sharpen filter. Yes the texture is more defined, however it also makes the pixels that you don't want to be more defined too defined and the color of some pixels that are RGB based will show up as bright green, red and blue, making the texture look like crap.
How to make it better;
1. Start from scratch and lower the sharpen filter.
2. Highlight the areas that are not so defined and low resolution and sharpen them.
3. After using your preferred sharpen filter try to blend the colors around the sharpened pixels to match the rest of the unsharpened pixels surrounding what you just sharpened.
As it is right now I can only give you a 4/10 because it looks like you highlighted the whole texture and then clicked the sharpen filter a few times.
Try putting a little more effort into the texture blending by using my advice and I will give you a better rating. ZacharyPw
