Good attempt, just remember that if you are new to smudging that it is never a good thing to also smudge the renders primary lines unless you know exactly what you are doing otherwise you'll destroy the render.

Also watch your quality, use high quality renders/stocks so the end result won't look too washed out or the colors won't look too burned.

I would say use regular fonts for the text for now, fancy texts in a signature lower its quality by a lot. The rest is regular things you need to work on like Depth, Focal, Lighting, Quality, Adjustment layers etc but one step at a time. First you must get the entire concept of a tag down before you work on these things, so best of luck and keep it up.
