This is nice. I love it 😍

I think it turns out really well for the first time digital.I really don't want to critique anything I just want to say embrace what digital has to offer, experiment, try brushes, textures, layer types, gradient maps...just play. I think you will discover some pretty unique additions to your own style.

Nice staline . Keep it up

First, you did a great job capturing not only Mayweather's likeness, but also that cocky/mischievous eyebrow raise he does. I think overall the proportions look good, even recognizing it is caricature-esque so his head is enlarged a bit. The only read constructive criticism I have is that in some places you seem to not have been able to decide between lines to define shapes or values. For instance, on the abs, you have heavy lines delineating the abs but also tonal values. Personally, since you are going all-in on the color and tonal values, I'd remove the lines. He has pretty deep-cut abs in real life but the dark lines make the abs look like lumps of clay stuck on instead of rounded masses with skin stretched over them. I think the tape on his hands is kind of tough because there isn't a lot of detail in the original photo and you can't really see much of the underlying anatomy even in the photo, but intuitively your eye knows it should be there so maybe imply more of that with the shading on teh tape? Your shading on the tape seems to be quite a bit darker than the photo so maybe that is what I'm responding to. But to keep that in perspective, it is a very minor point. If I were your professor, I would not deduct any points for that. Just something to explore. The main issue to me is the uncertainty between outlines and values. Outlines define a shape by painting a boundary around them. Values define the shap by showing how the light bounces off of the form. It is really difficult to mix the two without ending up with a visually confusing image. The anatomy, overall, is pretty good but in the neck area you seem to be unsure of yourself or of the underlying forms. I struggle like hell with this area as well. I think for my own work I need to forget it's a neck and just focus on the basic shapes, cylinders, but paying attention to how the muscles curve around the neck and where and how they attack to the top of the sturnum and base of the skull. Overall I would give you a solid B, maybe A-. The only reason I would not give an A is the issue mentioned above but it is a really nice image. I could not do anything even remotely this good digitally or otherwise so it is pretty solid.
