To say " awesome " or " excellent" would be a simple understatement.
First, the background is simply amazing, the moon and clouds look so realistic and close, the dark sky with it´s little, bright stars is just indescribeable. As well as your character. I really like his design, the black marks in his face and the cream white stripes around his spines suit the dark colour perfectly! As well as the bright purple on his boots! ( man, I really like the effect of the stripes, it looks like ivory )
Your technique with the shading is awesome, too! I like the thin white line which goes with the shading!

But there´re also some negative things.
The very first thing I noticed was his levt leg. Is it anatomically even possible to move it like this? You should have drawn the shoe more from it´s bottom instead of the side. I know you used *Honey-laurel17´s lineart but that doesn´t mean you couldn´t fix it a bit. The hand looks quite fine to me but the fingers got a little big.
The grass is more like a thorn in the flesh. It looks so simple and blank. A few more details like a flower, light effects or shading would have been great!
Also I think the eye, the litte part between forehead and nose, looks a bit too shaped. A little curve or something would fits it great but I think that´s a matter of taste

Sure, there are some things you could improve but the all around look of the artwork, the coloring, this .. effect.. I can´t take my eyes off, honestly. It just blew up my mind
Keep drawing such amazing art ~

Well I must say that you did an amazing job my friend. The background has lots of detail, the moon seems pretty close but I like that, nothing wrong with that. I do have 2 things that bug me just a little. The shoes are just a little off, it starts off skinny then out thick. I could be the style so I could be wrong on my part. The other thing is the right hand. Hands are really hard and I know that lol Now if the fingers are at the same hight, that means the bigger ones are pushed out more from the top. I'm not sure if can see what I see on that part but it's not that much of a big deal, the pic is amazing, you've improved a lot. If you wana improve more on your hand poses, draw refs from any other artist that love their hands on. I practiced a bit on Shadow Will's hand ref sheet, helped me a lot. Great job man!
