It's good for one to know they have room to improve, but never call your work crap. All creations are of value.
I would suggest less saturation on the blue in the ocean to get a more subtle look (Ocean water isn't that blue and if you look at old maps oceans are just the color of the paper plus or minus waves drawn). The large river at the east of the continent looks like it isn't actually a river because it is connected to the ocean on both sides. If it is not a river I suggest cutting or erasing the land area rather than applying a blue brush stroke over the land so that the drop shadow and stroke(?) effects on the continent layer is seen on the borders of the 'river'.
I think the outline is very good and I like the shading on the mountains. Keep it up
