Galina, I started like you, about a year ago; I learned a lot from googling everything on the internet and by asking a lot of questions to fellow cake makers, mainly on this site. My only advice to you (which I am really striving to achieve myself) is to work on your edges (cakes who are not carved). I like clean and sharp edges on my cakes and I did not yet achieve the look I want. You have many online tutorials and you can also purchase classes through craftsy! Good Luck!
