Hello, I would like to do this job for you.
I have a lot of experience in manipulating photos on photoshop, I just did this picture yesterday and the client was very pleased.
I also work with digital painting, being that it helps in the aspect of things looking more natural in photo montages.
If you can provide me the images and specify what you want and where you want it I'm certain that I'll be able to do a job.
I only have an old montage in my portfolio, but if you want I can show you the job I did recently.
Hope we can work together.
