The Viking theme is done perfectly, not missing any elements that would make me second guess myself.
Basic and bold shapes are used neatly, and proportionately.
Blue Gray Brown. 3 main colours used = neat + looks like the colours are smartly used.
Not overdoing small details such as the cracks, and chips on the axe. Nice textures as well.
There is nothing I can think of to add or change.
Great job on the design! 5 STARS

Please use your wisdom to help critique my artwork, if you may. THANK YOU! :D
It would a great help to improve my drawings + design in general.

I like your Dragon theme!
It's a clever design, because all the dragon elements are here (claws, wings, reddish brown colour) so I can immediately recognise it's a dragon theme.
I like the main colours you used "Black, reddish brown, yellow" these colours used really pops out! Plus the simple shapes used fits nicely. You can immediately see what design part is where, without getting lost.
I especially liked dragon egg wand design.
There is one thing that I would change, and that is, change the belt into a red cloth like the scarf he is wearing. Or, change the scarf into something like his belt.
One last thing is, the belt could also be made out of gold? idk I feel the pants is not quite the same, as his chest armor.
But great design in the end!
I hope my advice has been helpful to you, and keep up the GREAT work! :D
I'll give you 5 STARS!
If it's alright with you, please help review my artwork, so I can become a better artist! thank you.

I like your devil, Skull Jane theme!
I like the main colours you used "Black, Brown, White" these colours used really pops out, and the colouring used in different areas is good!
I especially like the spikey feel to your design, I can see that you made sure that your design have a lot of triangles, giving off that feeling of spikiness. Plus, both Jane's eyes and skull eyes are blue :)
But there are two things that "I" could change:
1) I would give her symbol on her hat (perhaps another skull symbol)
2) make the skull on her wand be made out of Crystals.
I hope my advice has been helpful to you, and keep up the GREAT work! XD
5 STARS!
