Why is this an M rating?

Ugh!

Can't you see that tail.Ä°t look like mace.Perfect!

weapions on a dragon?

don't a dragon have claws? don't they have a tail?
can't they breath fire? is this some kind of handicapped dragon???

I'm a bit biased but I like it

Striking pose, lots of detail. Anatomically good interpretation- the wings look like adapted paws, as they should.
As a sort of badge/logo its perfect, I suppose- red dragon person for Red Dragon with a apt background.

To truly inspire me as a painting- 10/10 it would have to resolve into a bit more detail on Full Size, with a more realistic look. It looks just a bit too shiny/plasticky perfect unlike a real, living character, without a flaking scale or a scrap of dirt, no craters on the moon and the wings are too symetrical for a figure standing at an angle. If it had maybe a nick out of an ear or a few scatches on the blade it might look like it had the neccesary experience to actually win that battle.

Your interpretation of the legs is interesting. The claws look like talons, as most dragons are given, but you have raised the animal up onto its toes, digitigrade like a cat or dog, with a dew claw. That would mean it is geared up for running, rather than grasping with claws from on the wing, like an eagle- which given that it has forepaws like a human, makes a kind of jack-of-all-trades sense for an animal blessed with six limbs.
