Prosta scena podwodna Model 3D

Hi, I am a VFX and Animation student, I thought it would be a good idea to upload my work onto TurboSquid, I'd highly appreciate some feedback on my model and what i can improve on. Hopefully I will be adding more scenes/models on here at some point too. This model took me 3 hours to complete, It is a very simple yet affective underwater scene, It contains a treasure chest with some gold coins and some pearls as well as a few different types of underwater foliage. I used a skydome light from Arnold to render. I created all but 2 textures. I created them on photoshop and they are very simple and easy, to make them i created a new square page and then put down 2-3 colours, after that I blended the colours using the mixer brush tool and then gave them a filter.
