Oh come on, you're brilliant if that are just regular pencils, it looks like you've done it with professional pencils, so I wouldn't worry about either wich brand you use. It looks realistic, the colors pop, actualy everything pops. Your sense for color is realy good and the way you mix them up is spotless! And satisfaction normaly comes in early stage when there are 100 positive comments. You already prove you have it in you, you just need to improve what can be improved.
You're welcome, mine is also, more working, laundry, cleaning and all the rest than that I can sit and enjoy the view while everything changes on my white paper, into a mushy grey/black/white sort of thing, that suddenly gets more shape in the end, it's more fun ^^.
