OK, if you could do the first one it would be great! there is a lot of details because she is picky 
would you be able to zoom in a little bit? the rough draft I made is a little different.... so i guess like this:

The scene is underwater (she is a new Greek water goddess) so yeah, shes underwater 
the boat is a Trireme (this is a trireme: I don't how well I drew that
)

Except its a little smaller than that....
the boat is old, so there is moss and algae on the boat. (the boat is also half sunk in sand)
The sails are ripped, and well.....old
The girl has Green eyes, freckles under her eyes and on her nose, and round, black glasses.
Her hair is blonde, and she wears it in a braid. it goes down to her waist. she is Caucasian, but really tan
I don't know if you'll be able to see this in the end product, but on her right (your right) ear she has an ear piercing at the top of her ear, and one on the ear lobe. and on her left ear just one on the ear lobe. (she just wears normal small "diamond" [fake diamond but yeah...] earings)
She has a brave facial expression
she wears a black Adidas sweatshirt, and light blue destroyed jeans (with rips on her knees) she also has green all-star converse high tops.
(i almost forgot to add.... she is a fourteen year old girl)
she is holding on to the mast with the left hand (her right hand) , and holding onto her sword with the right. (her left) I guess she is standing on the rim of the trireme.
her sword is gold, and there is a greek word engraved on it, νερό (Greek word for water) but on the sword, it goes down about halfway on the sword as
ν
ε
ρ
ό
And one last thing:
can there be ocean plants growing out of the sand?
The book title is The First Dawning (title at top of cover [my friend isn't going to put her name on it]).. and if you are able to, could you type it in a font like this?
If you aren't able to find that font, that's totally fine! 
Thank you soo much! there is no rush, but are you able to be finished in a month or two? If you need more time than that, that's totally fine! 
sorry there was so many details... I have spent the last 30 minutes typing this 

Thanks again!!
