I been braking my head trying to come with a nice pose that picture the two characters of this comic like cover. 

I try many other but this one is the one i like the most.

Think this will work, Lake shemale monster in her element, she is in the water and you can see her sea like mermaid/snake like bottom part going a far in the picture, ( the pick is a little cropped down there, sorry this is only to judge the pose) wile our hero is sort of cough out guard by the creature, clearly in a advantage as she is in her element ripping her top out and fisting her anus as groping her with her tentacles with a lascivious look on her eyes and a raging erection i will cover in water plants later as she is emerging from the water; haven't drawn her tentacles yet, again this only got the pose. Anyway please let me know what you think
,,,

 Sketch with details! I suppress the tail in the background as looked a bit confusing and unnecessary saturated the composition; also add a shell like top for the monster, i mean she has a weird sense of fashion or loved "the little mermaid", anyway, please let me know what you think.

Line work , whew! took me forever to do!

No urethra insertion Sorry, don't think we discuss that in the initial description, or did we? but anyway, the monsters has only two tentacles, the end of one is in the left breast milking her left nipple and the other is being grip in the hands of the heroin; she s string to get lose and there is a strugle and wanted to show it there;  also the momentum of the scene will be bother if the tentacle is penetrating  the cock as first its already ejaculating, i will go in that in deep late, but also she is ripping her cloth, i mean she is dominating her so the cloth ripping is going over her cawck, now she is ejaculation, but is because is a prostate orgasm, if you see her the lake-monster has her thumb deep inside her anus stimulating directly her postate and making her ejaculate involuntary, that is why she has that expression in her face between scare and surprise.
...
Cell shade colors ready! I wanted to emulate the colors of classic comic covers but the colors where to hard so i decide to go with the cell coloring which fit.

Please let me know what you think.

I know we didn't talk about a back ground but add a pretty one with splashy effects, nothing too over complicated just to set the atmosphere of a lake and that our heroin is in a disadvantage as she is fighting in our emerald monsters territory.
Hope you like it!
