Take the actual photo to Costco Photo, they can turn it into an canvas, with frame, cropping and retouching.

I'm sorry, I don't understand the question.

You said you need photoshop help, but then you asked for arrangement options?

Grouping ideas?

it looks like the Sea Glass Giclee print is 40 inches by 40 inches square, and 1.75 inches thick. i would look for another abstract print in similar colors, or a photo of water/water scene, that could be framed to be 40 inches tall, but not as wide. or several smaller prints/photos which could be mounted beside the Giclee.
(p.s. your doorway is probably standard 80 inches tall, so i used half that for the 40 inches)

ha, look what i found on Houzz!

Amazing what you get when you reach out for help! Thank you!

Great idea Teri...they could also be mounted so the "lines" run vertically. The colors could be mounted with the dark in the center or the blues in the center.

I wish two were in the budget!

That is a cool idea Terri, I like the idea of them going vertically too...you could change them.

I have a piece similar to it, if you are interested. Maybe I could work with your budget to do two.

Sorry, I didn't read the question thoroughly
