i can see that you have s ome talent with 3d work as that background is very nice and has alot of detail to it, the fire
looks out of place as it doent mesh with the background it sits on top not complimenting it, The character is nice but
same thing with the fire the character doesnt seem to be apart of the background.
i Understand that you have spent alot of time on this and all it realy needs is alittle more.
heres an idea that i have just had may take you a couple of more hours, anyways, try reversing the character and making
her smaller, put her at the back ontop of the water, she is creating fire with her hand so she has magick so she should
be ok for walking on watter, just add a rippled reflection of her on the waters surface. Since the character is reversed
it will lool like she is loking back over her shoulder from where she came, try improving the fire abit by making into
more of ball of flames, think around the terms of what a tennis ball would look like if covered in fuel and set alight
that should help give you a better idea on how it should look.
Anyways like i say great work on the background and hope this rambling on has helped you in some way
