Copy from SAGD, I don't think this is the whole post but I'll edit it.
Two nights a week (can obviously spend as long as you want), instead of watching movies / series or playing diablo 3. You spend time drawing something. It doesnt have to be blizzard quality, obviously, this is just a SKETCHgroup. The primary goal is, practise, and good design.
There will be a theme, like, Sci-fi Dinosaur Cat hybrids of the future. Heres where we practise drawing things like this.
The one thing the themes won’t be, is; Draw a goblin. Draw a robot. This is boring and doesn’t help anyone. And more offen than not in the games industry (expecially in indie games) the ideas for monsters / environments / characters are never this easy.
We can alternate the weeks during the month, First week character design, second creature design, third environment / prop design, forth vehicle design. You should be able to part take in all of them. If you say that you only do characters I will fly through the screen and beat you with a ham. In art, if you know your fundamentals, you can draw anything. And you should be able to draw anything, in small teams its out of the question to hire 4 artists to do 4 different design jobs. The person who can do it all will get hired.
We could also mixe it up and do a week where we have to sculpt a concept. Also we could have a set model (obj or fbx) that everyone can download, and its already been unwrapped, and you have to PAINT the texture. Painting textures is something EVERY game artist should be able to do without a problem, NO PHOTO TEXTURES.
So lets get to it and come up with some themes?!
EDIT: If you are new to game art, you might be asking what do I use to participate in a sketchgroup.
1) Pencil and paper (you can’t go wrong), No excuses.
2) If you wana draw in photoshop, go buy yourself a R300 genius tablet, you can get them anywhere. No excuses.
EDIT: You can add an optional extra to your idea, to help the design, IE: (This character is great at setting traps), you don’t have to follow it to the T but it might be nice for someone that is looking for a bit of an extra challenge.
EDIT: My opinion: What is a character, What is a monster, what is a vehicle, what is an environment?
1) A character is usually playable or an NPC (main story characters), these guys have gear, and are usually designed to be easy for a viewer to relate to.
2) creatures are basically everything else organic in a world. Everything from badass monsters, to squirmy earthworms. This can be a bit blurred with characters but the basics are there.
3) Vehicles, self explanitory, but can also include things like the oilifants from lord of the rings.
4) environments, you usually want to create a world that looks like it could be played on, or inhabited by something. Real life landscapes kind of fall into this but for game design we want something more interesting and more condensed.Prop design and achitechture design also falls under this catagory
