Wow, that's a big map As always, exceptional mountains! The forests are not bad, but they could use a little more omph, imo (also, i think you should make them a little bit more visible...they are too lightly colored imo).
Coastlines are nice but the continental-shapes are a bit...weird...as is their overall placement (then again, this being a commission, i don't think you could do anything about that).
As almost always with commissioned maps, i'd wish you could upload a higher res. ... i so want to go into more detail with this.
Have a Like (as usual) and i checked, i can finally rep. you again...so, have some Rep.!
Edit: Oh and what is the scale on this map? I really think mappers and commissioners should think about putting scale bars in their map...it helps so much in putting all into perspective and it can give a totally different view on a map if you know the scale of it.
