I'm a working mid-level product designer in the UK, and have always just 'got by' with my sketching ability. I would like to improve, so I'm starting this thread to spur my dedication and have people provide feedback on my weekdaily sketches.
I'm planning to come into work an hour to an hour and a half early each day (hence weekdaily sketches), sketch for as much of that time as possible, and post the results here and hopefully improve over time with your feedback.
On today's sheet of bike-touring focussed GPS units (attached), I stuck to lines and no shading. I have plenty of observations on what could be improved with this sheet; perspective, proportion, poorly placed shadows, etc. but if anyone has any thoughts on how I can look to improve I'd appreciate it.
