Hi Staciarain, water problems huh? Well lets see if we can fix that for you.
I haven't got a link to a water tutorial right now but will see what I can do and will also work on a lesson for water for all those interested. Water is more a perceived difficulty because it seems daunting,especially an ocean. If you break it down into light and shade and sections, it becomes more manageable and less daunting.
Can you post the drawing you're doing so I can see what you are trying to create and help you more? Also are you working from references in your drawing of the pirate girl and ocean or is it out of your imagination? If it is the latter you still need references to make the image work and provide the realism to the image that you're trying to achieve. If you are drawing from a reference image for the ful drawing, then you need to carefully observe areas of light and shade and apply them to the drawing. I know, I know, easier said than done.
hang in there, we'll get you on the watery path in no time!
