The render is a bit noisy, I suggest using a denoiser or just turning it down a little. You could’ve added a few overlays to make it pop out. The lighting on the render is very nice and it fits with the color of the text.
You could do a lot more with this! Maybe some cool little effects like glitching, or other filters on the image. A background would also look nice, and maybe some gradient on the text? I love the lighting on the character, but as @VizPoptartz mentioned, try your best to remove as much noise as possible! Turn up your cycle counts if necessary!

I love your avatar in the GFX, and your shadows as well. But the text gets to me. The text cuts into your border, and it makes it look cluttered.
Not bad, although I personally think the text is a bit large. The avatar in the corner looks quite good!
