The 5 is a little taller than the 2, but it's clear and easy to read so I'll give you a 9.5/10, which should be added to your UNO score sheet under the "Draw Evaluation" section.
As I'm sure you know based on the official UNO rulebook, your Draw Evaluation scores will be averaged at the end of the game and then Average Draw Evaluation (or ADE) will be added to your other overall metrics such as ACH ("Average Cards in Hand") and SAC ("Summed Attack Cards", generally defined as attack cards you have played on others minus attack cards played on you, but some house rules assign different point values to different attack cards).
The metrics you choose to play with in any given game is of course something to be discussed with all players beforehand, but competitive UNO will of course utilize all standard metrics.
Did you know: the "Card Color Multiplier" metric isn't a standard metric? It's basically the Free Parking of UNO - very popular but not officially recognized.
