Hello! On this post I wanted to show you my drawing steps over my profile image. I can share more posts like this if you want. 😊
I usually start with rough sketch. I do the sketch with medium airbrush.
Then on new layer, I define the sketch. I used medium hard airbrush this time.
I’m not a patient person, so I start lining the drawing next. 😅 I recommend you to define and add details to sketch beforehand. I use 6B pencil for lineart. I like sketchy look of it.
After I lined everything, I add some hard shadows with same brush. 
Now we are ready for colours! I do flat colouring first then add some textures. I use technical pen brush for flat colouring. For textures, I use bunch of brushes which I can’t name all of them now.
Where almost at the end! For shadows, I use a watercolour brush I downloaded. I usually use purple shades and set layer on multiply.
Let’s add some light now! With the same brush I add some shine here and there. I use orange shades for this one and set layer on add mode.
We’re done! I hope you enjoy the post. I can do more detailed posts in the future. This became a trial for me too. 😁 If you have any question or request please let me now 😃
