Tips:
Be VERY mindful of how the person draws their O.C. If they draw it extrovertly, do not draw it introvertly, and if they use a solid form, do not make it fluid
Using your style to draw them is absolutely fine, but don't let it take away from their features or traits.

Tricks:
-Look for the patterns
Artist who post submissions tend to not only show what they like to draw, but also what they like to see; both through submissions and favorites. Draw their O.C with a few of their traits, but more of yours. They don't want to get an exact replica of if they drew it themselves
-Ask them what they think about your work
-ALWAYS ASK ABOUT FACIAL EXPRESSIONS!

Tips: It is very important to be TIMELY
Always remember to mind how the O.C behaves. If they are courageous, don't draw them being cowardly.
-If they are cocky, do not draw them as timid
-If they usually strike an extrovert pose, do not draw them introvertly
-If they are usually humiliated, do not draw them humiliating others
-if they have sharp features, do not make them bubbly
-if they are buff, DO NOT draw them skinny. THIS IS VERY IMPORTANT
-If they have a solid form, draw it in your style, but DO NOT COMPLETELY COMPROMISE IT
-if they have small details that are hard to draw, ask the artist if they can be omitted

-Do not lessen/ shrink any feature without the artist permission
-Remember to ask the artist what kind of art they want before drawing
