How it works
Seven days to create something of your own.
The reference is the same for everyone. The style, the technique and the result are up to each artist.
Discover the challenge
Every week a new reference image is published, designed so you can approach it with pencil, ink, watercolor, gouache, digital media or any other technique.
Draw and share
Interpret the image in your own way and upload your work before the deadline. The piece must be your own and follow the community guidelines.
Open the gallery
When the challenge ends, everyone's contributions are revealed. Compare decisions, learn from other approaches and celebrate the variety of results.
The gallery opens at the end
One reference, many ways of seeing.
During the challenge you work without being influenced by other people's solutions. When it ends, the community becomes a collective exhibition.

New · CronoSketch mode
Train your strokes between challenges.
CronoSketch is a personal training space: timed drawing sessions with reference images to loosen up your hand, sharpen your observation and build a rhythm. Nothing is published or compared: it's just for you.
Set up your session
Choose the difficulty —easy, medium or advanced—, how many images you want to draw (from one to five) and the time per image, from 30 seconds up to 10 minutes.
Draw against the clock
Each reference appears full screen with a countdown. You can pause, add 30 seconds, skip to the next one or lean on the study tools whenever you need them.
Track your progress
When each session ends, your stats are saved: minutes drawn, day streak and session history. Star your favorite references and revisit them whenever you like.

SketchChallenge is born as an open space: no fees, in-app purchases or subscriptions to take part in the challenges.

Frequently asked questions
Before you start.
How much does it cost to take part?
Nothing. SketchChallenge is planned as a free service, with no payments or subscriptions. If this model were ever to change, it would have to be clearly communicated before applying any economic conditions.
Can I use any technique?
In principle, yes: traditional drawing, watercolor, gouache, pencils, ink or digital media. Each challenge may state specific limitations when necessary.
What is CronoSketch mode?
It's a personal training mode built around timed drawing sessions: you choose the difficulty, the number of images and the time per image, and draw from references with tools such as a rule-of-thirds grid, mirror or grayscale view. Its goal is to help you loosen up between challenges; nothing you do there is published or takes part in the voting.
When can I see other people's work?
The collective gallery opens when the weekly deadline ends. That way each participant develops their own solution without unintentionally copying other users' interpretations.
What rights do I keep over my drawing?
The authorship and rights over your work remain yours. By uploading it, you grant the platform a limited license to host it, display it and promote the service itself, as detailed in the terms of use.
Where can I ask for help?
The support channel is still being set up. In the final version, help will be provided from soporte@TU-DOMINIO.example.
