Making the focal nice is very important so i would advise to prep it before u do any work on the tag. Things like denoise and color tweaking along with sharpening to start off. To me, it gives u a better base to work off from the start.

Pay alot of attention to the render as far as where the light should come from. On this pic, her right side is pretty dark and the left side is well lit so i would say the light source should come from the left instead of from above.
Don't forget your photo filters..most times than not, they will tie all the colors and tones together instead of having the mismatch look.
Lastly, the text. I know this is giving you some probs and most ppl struggle with this. Just try to match it with the tag; try and get a feel from the tag to help in font choice and position.

Keep up the good work..i like this style!
