I deliver in .jpg and .png format. Hy my name is Ciprian Gheorghe, I am a student at one of the best universities in my country at the industrial design department. I'm sorry if I misspelled I am not a native English speaker. - I have over 7 years experience in Graphic Design (Photoshop, Ilustrator, etc.) , and 5 years experience in photography(so I have a creative mind). -I guarantee a elegant / clean design. Considering different time zone maximum duration can reach up to 2 days but I do not think it will be any problem because I am awake nearly 18 hours a day.
