I like the Latios and Latias alot. One thing I personally prefer is thinner lines for certain things, as they look sleeker and refreshing I guess, so Id suggest you give it a try. Also, highlights are pretty easy to add by going to the color wheel and heading toward a bit more white. Then apply this new color to yhe highlghable areas. Experiment with this and your drawings will really look 3D. Keep up the good work!
