Did it in photoshop with photo reference for pose.

The arm on the right (that would be ours not hers) appears to be coloured black under the breast for no obvious reason, on that same arm the hand needs a little more definition between the thumb and index finger as its making the thumb look a tad short, as an aside perhaps colouring the nail with nail varnish red to match in with the belt would be a nice touch.

The shadow under the left arm (ours again) is perhaps a little too deep although it does cause nice contrast and in that area, perhaps the bakini strap should be a touch darker it would obviously be shadowed as well.

Last few points now! Onto the face the left nostril is staring at me! perhaps a little smaller or toned down a bit and my final point the teeth could be a little whiter, oh and really my final point perhaps more definition in the hair but i'm thinking that might be there already (just a resolution issue) unless you intended it to be unfussed if your going to ad text over it etc.

Hmmm just read through that and i noticed quite a few things! Now onto the nice touches i liked the jeans very much though the fly seemed a bit to the right *looks down and checks his own* although thinking about it thats actually how it should be well observed! The face is a masterpiece looks fabulous and the pose is just right sexy and fluent looks like shes really moving... Dynamic was the work i was looking for.

-EDIT- Just saved the picture and checked the properties some of the too dark colouring could be from the JPEG creation when it changed to sRGB mode just a thought, in fact almost all of my comments could be because of the conversion to JPEG...

Feel free to come btw guys, though the only information on it so far thats definitely correct is the address and the date, and the bar name. And the phone numbers.

Had a play around with a few fonts on the background and found that "wild words" gave a nice clear easy to read finish. If you want it (and dont have it i can send you the font pack, think i have it still here somewhere) i have attached a sample of the text for your perusal
