Iszeldier Traditional

Here's a character design and traditional practice for my character Iszeldier. I have done done traditional art in such a long time, I feel really rusty.

What do you think I can do to improve my style here? I'd really love critique for this. As for mediums I have at my disposal, I have colored pencils, watercolor pencils, acrylic paint, oil paint, and copic opaque white, just to give you an idea of what I have by way of traditional media. What do you say? any tips?
