What quality of photo you provided is what you'll get in your portrait artwork. (I'll follow your photo's face emotion, hairstyle, skin colour, lighting, etc) I based on your photo to draw your portrait, the more details I can see, the more details of your portrait to be drawn.
I use Adobe Illustrator to draw your portrait, the final resolutions of your headshot portrait size is approx. 400 x 400 pixels. If you need to print large or any reason huge, you should consider purchase my vector file which cost extra. Vector is a file let you scale your artwork to any big size without losing quality.
Normally I will complete your order within 2 days, depend on the amount of orders and your photo quality.
