Destination Orthodontic LabLogo Design Contest

We make retainers and other orthodontic appliances for Dentist and Orthodontists. We do not make crowns or dentures. My target audience are Orthodontic and Dental offices.

My lab colors are a aqua blue (a mix between brilliant blue and turquoise-not aqua) and Lime Green (not the highlighter lime green, a little darker than that). I actually loved my very first logo, but I need something that looks more professional and not like I did it from paint.

My current logo has a palm tree, a sun, and waves and just says my full business name under it. I would like all these things to be incorporated in my logo still except I am leaning towards my logo just saying "DOL" instead of having the full name, then including the full name on things when I need too.

Things to incorporate in new logo:
-palm trees
-waves
-sun
-the initials "DOL"

I attached my first logo I used (all black), the one I am using now (in color), and an idea a friend had.

I want my logo to look professional, clean, modern, dreamy (like how being at the beach is!), and I want it to POP! I am open to it having a 3D look too.
