Okay, to start anthro type works are not my forte, so I'll try to focus more on the technique than the subject matter itself.
The playing card set up you chose was a interesting choice in the best way possible. It adds a flair to the picture and plays on the fire / water contrast you have with the two characters. The colors are superb (which has become par for the course when it comes to your work) the tones for the main body and the underbelly work very well with the element theme. The fire dragon's hair and tail are especially well done. The bold lines are appealing to the eye and the dull brown background makes the characters pop.
Now for the critique. The teal and red designs behind the dragons kind of blend in. I found myself confusing them for parts of the dragons. swapping the colors of the designs may help the composition a bit, putting the teal design behind the red dragon and vice versa.
Now the actual dragons themselves. I feel they are stuck between feminine and beastial. it looks like the red dragon is supposed to be more fierce while the teal dragon is to be more slender. But both are stuck somewhere in the middle. Again, anthros are outside my area of expertise so if it is supposed to be more of a mix then well done!
All in all as I write this review i find myself liking this piece more and more and hope to see more work from you in the future.
Thanks a lot for the critique. I hadn't gotten a proper one in a while, and it's much appreciated. I'm probably going to darken the shades of the teal and red background designs instead of swapping them, cause I tried them swapped while the work was still in progress and it just didn't look right to me.
As for the characters themselves, The red one is already a recurring character of mine that's supposed to be both fierce and feminine. Though I'm not exactly sure what I want the teal one to portray. Haven't really come up for a personality for her.
