Nice Colors
Every aspect of the drawing does excellently in portraying a realistic take on the usual anime-style of Digimon. Although the line work is dark enough to match an animated portrayal, it provides details of texture for Garurumon such as adding a softness to the fur, "PROVIDING-DEPTH" to the drawing overall. The details, in general, also give depth to the entirety of the drawing. The color scheme complements the "YELLOW-GREEN" outlining, and the blank white background gives it a pop.
~~THINGS TO IMPROVE ON~~
Maybe a border or frame or some backround detail.
