No problem at all. There is plenty of tutorials online, just need to search for it.
Word of advise is to focus on your fundamentals first and not to worry about the more advanced techniques. Get your composition, anatomy, gesture and form right and everything else is just a bonus. And practice. Lots of practice. lot of lost of lots of practice. I can't stress this enough.
Not sure what is your level of inclination and if you are naturally gifted but I keep saying my talent run out when I was 4 years old. Everything after that was hard wok.
It is going to take time but everyone can do it.
And good luck
