Hey, I know the reply is a bit late but maybe its still helpful to you. The eyes look very good but lack some refined details Tip: Adding more highlights and defining the shadows more, will add to the overall quality and realism. Also, if it comes to light reflection, you can think of the eye like a jewel or a marble. The buttom of the eye is the most bright part (but also add some shadow at the very buttom, again like a marble), while the top is the darkest. Also, the reflected light dances inside the iris. Its like the light is bouncing inside the eye. I hope this helps

nice job

The first one is good, the second one not as much. James Gurney always says that he recommends new artists, who are just starting, to avoid style and concentrate on depicting the natural world as close to real as possible. Your cross-hatching, even though it might be your preferred method for rendering shadows, is interfering with the depiction and understanding of the forms. I will add that, if you want to depict shapes and shadows through cross-hatching, I recommend Alphonso Dunn's videos on YouTube, and also his book "Pen & Ink Drawing: A Simple Guide". I hope this resources help you in your journey.

Awesome! I like how you tried different expressions. The forms feel really solid too.
