Correction of an essay

stecoondra:

Hi,
I'm doing a very important English test next month and I need to prepare well for it.
The test includes writing an essay.
I've written one but I'm not sure whether is it correct or not.
Could you please check it ?
Thank you very much.
It's very important for me .

Dear Sam,
I’m very pleased that you’ve chosen me to paint and also I’m looking forward to it because I’ve never experienced something like this in my life and I think it’s a great experience.

I was thinking about the place and I reckon it would be best if you painted me in our hall. I’m sure you remember how it looks but if no I’ll describe it to you. There’re many paintings, sculptures and an old wooden chair. I’d like to be painted in this room because me and my family are very proud of it.

It’d be great if you could paint me with my little doggie. He’s so adorable and cute. He is my best friend and I love him so much.

And there’s one thing I’d like to ask you about. I don’t know what should I wear. Please tell me what should I wear.

I’m looking forward to hearing from you soon.

Mark
