Some critique on the rest of the map:
It's hard to tell what some of the labels are meant to label. You have names that sound like point names ("Gora", "Tochka", etc), but they are positioned as if they are names of large areas. I get that this is a fairly large-scale map, but it's still hard to tell whether some labels are meant to be for a single mountain or for a group of mountains, or for the flat area next to the mountains. Particular weird points:
Slomannoy Gora is positioned along what looks like a ridge of several mountains, an effective technique for the title of a ridge, but its name implies a single peak. Adskaya Gora is similar, but there the ridge appears small enough to be called a single "gora".
Nozh Tochka appeals to refer to the low area southwest (right and up) of the mountains, but its name also seems more likely to be to a peak.
You did an excellent job with the river flows and elevations. It's so good to see a map in this style that doesn't have rivers flowing uphill. At first glance I thought some of the rivers flowed opposite to how they do, but I think that's just because of my brain equating the green forests near the upland lakes with lowland.
Your compass rose appears to have East and West switched, is that intentional? That sort of switching is common for sky maps and other things seen from below, but if we're meant to be looking down at terrain from above, it should be the other way. Or does this planet spin in the opposite direction to Earth?
Lastly, I think the fantasy creatures feel a bit out of place. Not by their presence, which is fine, but by the way they're drawn. The line style on them feels a bit different from the line style elsewhere, it's thicker and smoother. The colours on them are found nowhere else on the map, so they draw too much attention to themselves.
